2 Claims. (Cl. 173-328) 'I'his invention relates to sockets and more esposition. In this way, the socket structure? is pecially to sockets for use in connection with maintained in assembled position by the lug vacuum tubes and the like. An object of this prior to its being riveted in position on chassis l5. invention is to devise a simple and cheap socket In the event that the socket is located in an 5 which will have means for orientating the pins of inaccessible position, it is only necessary to look 5 a plug such as are commonly used on vacuum at the tube base and locate the large pins I6 and tubes whereby the proper pins may be inserted then feel for lug 2D. The tube may, thereafter, into the proper apertures. be plugged into position correctly with a minimum Referring to the drawing, Figure 1 is a plan of effort. l l 1 view of my improved socket. I claim: p 10 Figure 2 is a sectional view on line 2--2 of 1. A s ocket comprising an insulating base, a Figure 1- plurality of Contact elements supported by said "The socket comprises two layers of insulatin base and dependingtherefrom, a thin insulating material I and 2 of phenol condensate product sheet superimposed on said base and contact l5 or any other suitable material. Each of these members and having a plurality o apertures l5 layers is provided with a plurality of registering vwhereby access may be obtained to said contact apertures 3, 4, and 5. Supported on bottom plate members, andan elongated guide in the form of I and beneath plate 2, are a plurality of contact an individual piece having means for attachment clips I0, depending through apertures 3 to 5 to said socket, said guide located above the surinclusive. Each contact clip I0, has a soldering face of said insulating sheet and extending along go lug II,depending through suitable slots in plate I. said surface from the outside to the inside` oi Plate 2, is superimposed upon .the contact clips I0 the region bounded by said apertures, said guide t0 hold them against upward displacement, A adapted to act as afeeler thereby to facilitate the pair of rivets I2 and I3 is provided for rigidly Correct entrance 0f a Cooperating .tube Das@ im@ maintaining plates I and 2 together and sup- Said COXltlCt elements. l
